Hello everyone, We came across a critical (release-blocking) bug in Xubuntu with locking, user switching, and guest account. After completing a more in-depth analysis, we found similar and related critical bugs also affecting Ubuntu.
It seems that switching between two normal users (not guest) seems to be successful in both Ubuntu and Xubuntu (the latter when using gnome-screensaver instead of light-locker). Ubuntu: Guest login crashes https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1627304 Xubuntu: Guest session fails to logout https://bugs.launchpad.net/ubuntu/+source/xfce4-session/+bug/1627310 This investigation originally started from the below bug, where we found that a session locked with light-locker/lightdm fails to resume. Xubuntu: Fails to unlock/ resumes to black screen https://bugs.launchpad.net/ubuntu/+source/lightdm-gtk-greeter/+bug/1622303 We're opening the dialog here so that we might be able to get several eyes on it. These issues may negatively impact the other flavors in unique and related circumstances as well. From what we can tell, Ubuntu MATE does not seem to be affected.
